AlphaSTEM® Culture Substrate

Product Description

Cell Culture Surface Coating | 360ul 

AlphaSTEM® Culture Substrate is a mouse monoclonal antibody that provides a defined surface for feeder-free generation and expansion of naive pluripotent stem cells. AlphaSTEM® Culture Substrate binds to the MUC1* growth factor receptor that is expressed on all pluripotent human stem cells.  When used with AlphaSTEM® Naive hPSC Medium, AlphaSTEM® Culture Substrate has been proven to supports the naïve state in human stem cells and can also be used during reprogramming for high efficient generation of naïve induced pluripotent stem cells.

AlphaSTEM® Naive hPSC Medium and Culture Substrate deliver:

  • Enhanced feeder-free reprogramming that is simpler and 20 times more efficient
  • Efficient large-scale expansion using single-cell passaging while maintaining a normal karyotype
  • Superior directed differentiation with improved yield and cell quality

Keys to Success – Please Read Before Starting

  • AlphaSTEM™ Naive hPSC Medium media does not contain FGF2 and is not compatible with FGF2 media.
  • Culture conditions:  Hypoxic incubator (37°C, 5% CO2, 5% O2).
  • Rho kinase I inhibitor
  • AlphaSTEM™ Naive hPSC Medium is used with AlphaSTEM™ Culture Substrate coated plates.  The medium can be used with other surfaces such as MEFs and Matrigel®; However, growth over these and other surfaces has been shown to compromise naïve characteristics of the resultant cells.
  • The AlphaSTEM™ Culture System uses TrypLE™ dissociated single cells which grow in a uniform monolayer.
  • Passage cells at 75-85% confluence (~3-4 days). Do not overgrow the cells.
  • When first working with naïve cells, it is ideal to have existing naïve stem cells to use as a reference/control.  Minerva offers both male and female naïve stem cells lines.

A Primitive Growth Factor, NME7AB , Is Sufficient to Induce Stable Naïve State Human Pluripotency; Reprogramming in This Novel Growth Factor Confers Superior Differentiation.

Epub 2016 Jan 7.A Primitive Growth Factor, NME7AB , Is Sufficient to Induce Stable Naïve State Human Pluripotency; Reprogramming in This Novel Growth Factor Confers Superior Differentiation.

Scientists have generated human stem cells that in some respects mimic mouse naïve cells, but their dependence on the addition of several extrinsic agents, and their propensity to develop abnormal karyotype calls into question their resemblance to a naturally occurring "naïve" state in humans. Here, we report that a recombinant, truncated human NME7, referred to as NME7AB here, induces a stable naïve-like state in human embryonic stem cells and induced pluripotent stem cells without the use of inhibitors, transgenes, leukemia inhibitory factor (LIF), fibroblast growth factor 2 (FGF2), feeder cells, or their conditioned media. Evidence of a naïve state includes reactivation of the second X chromosome in female source cells, increased expression of naïve markers and decreased expression of primed state markers, ability to be clonally expanded and increased differentiation potential. RNA-seq analysis shows vast differences between the parent FGF2 grown, primed state cells, and NME7AB converted cells, but similarities to altered gene expression patterns reported by others generating naïve-like stem cells via the use of biochemical inhibitors. Experiments presented here, in combination with our previous work, suggest a mechanistic model of how human stem cells regulate self-replication: an early naïve state driven by NME7, which cannot itself limit self-replication and a later naïve state regulated by NME1, which limits self-replication when its multimerization state shifts from the active dimer to the inactive hexamer.
